AI Technical Summary
Traditional K0 consolidation apparatus suffers from pressure hysteresis, distortion of boundary condition simulation, and interference from friction effects, causing the measured static side pressure coefficient to deviate from the theoretical value, thus failing to meet engineering accuracy requirements.
A pressure control component controlled by water pressure and a sealed rubber diaphragm are used to form a closed pressure chamber to reduce friction effects. The permeable stone ensures the water permeability and drainage path of the sample, and a pressure sensing system and data acquisition module are used for real-time monitoring.
It achieves precise control of lateral pressure, improves the accuracy and stability of test parameters, ensures the reliability and repeatability of test data, and meets engineering accuracy requirements.
